I think interact is just as useful in research as in education. So
far I've used it
several times in research; and, several times in education. It's
great for both.
The functionality you request above with textareas is something I definitely
anticipated somebody else adding after the first version of interact. Good!
The same with the spreadsheet-style input for matrices, which I would
really like to see. Does anybody know of any good examples of javascript
that inputs a spreadsheet or matrix of values?!

To implement both functions you describe above you would probably only
have to edit the file
SAGE_ROOT/devel/sage/sage/server/notebook/interact.py
This definitely won't be trivial, but fortunately that file has lots of
documentation. You could probably get away with just modifying
the input_box and InputBox classes to have an extra options that
allows for a given number of rows and columns. Also, you might
need some clever javascript or a submit button or something,
to know when to submit the multiline input textarea.
For the spreadsheet, it would depend if it uses much javascript
or not. If it does, do something like the slider (and Slider) classes.
If not, it will be more like InputBox.
Happy coding!
